§ 17.12.030. Street setbacks.

A.

Measurement: For single and two-family lots the street setback shall be measured from the street right-of-way line. For multi-family and non-residential districts and non-residential uses in the R/R-A, RS/RS-A, AR2a and AG districts the minimum street setback shall be measured from the Standard right-of-way line as established by the table entitled "Standard Street Right-of-Way Widths" in the Major and Collector Street Plan.

B.

Street Classifications. All street classifications are as established in the "Subdivision Regulations of the Metropolitan Government of Nashville and Davidson County" and the "Major and Collector Street Plan" as adopted by the metropolitan planning commission.

C.

Street Setbacks.

1.

The minimum setback of a structure from an adjacent street shall be established by the following tables according to the zoning of the property and the classification of the street.

2.

When the rear setback of a corner lot is oriented towards the rear setback of a neighboring lot, the required street setback along the street common to those two lots may be reduced by fifty percent. A corner residential lot created by plat prior to the effective date of the ordinance codified in this chapter may reduce the required setback of Table 17.12.030A by fifty percent along that street running parallel with the side of the residential structure.

3.

In residential areas with an established development pattern, the minimum required street setbacks for the R and R-A, RS and RS-A and MHP districts shall be the average setback, up to a maximum of three times the standard setback provided in Table 17.12.030A, of the four nearest single-family or two-family houses on the same block face that are oriented to the same street and that follow the established development pattern. When there are less than four single-family or two-family houses on the same block face that are oriented to the same street and that follow the established development pattern, then the minimum required street setback shall be the average setback of all single-family or two-family houses on the same block face that are oriented to the same street and that follow the established development pattern. When there are no other single-family or two-family houses on the same block face, oriented to the same street and that follow the established development pattern, then the value provided in Table 17.12.030A shall determine the setback. In the MUN and MUL districts, the average street setback of existing structures along the same block face may be applied to new construction on that block, if determined appropriate by the zoning administrator to maintain or reinforce an established form of character of development.

4.

When a subdivision plat establishes a reservation of land for future right-of-way acquisition, the street setback shall be measured from the ultimate right-of-way line.

5.

Double frontage lots are subject to the provisions of Section 17.24.060(B). Property abutting a street designated as a scenic arterial by the major street plan shall comply with the provisions of Section 17.24.070.

6.

The front facade of a principal structure on a corner lot that has lot lines of unequal length abutting the streets shall be oriented to the shorter lot line, except where the zoning administrator determines that the longer lot line is more appropriate based on one or more of the following criteria:

a.

The longer lot line of a lot zoned for office, mixed-use, commercial, or industrial use is located along an arterial street as shown on the adopted major street plan;

b.

The proposed structure will contain multiple businesses with outside entrances;

c.

The predominant character or pattern of adjoining development is or will be oriented to the street on which the longer lot line is located.
